David Weber's "the shadow of Saganami"

I'm writing a sort of sci-fi space opera and I heard Baen books is a specialized publisher for this genre, so I thought to buy one of their titles to get an idea of what they want, and how they work.

I red a pair of reviews and I thought that the shadow of saganami would have been the closest match for my story, so I bought it.

Well, now I'm at page 179 and I don't know if I'll be able to finish this book, I was wrong, it's completely different from my project, there's the same relation between John Wayne's westerns and the revisionist westerns of the 70s...of course, my novel would be the "revisionist military sci-fi novel".

Anybody have experiences with this book and Baen in general?What do you think?
